Sure. You're spending your time doing something. That's probably to produce a product, or service, for someone else. In this case, it's the customer. So you put them first and foremost in your mind, and then work backwards to identify whatever process is suitable to create the product or service that meets their expectations. This ensures what you deliver is valuable. When we do this, it reinforces our own sense of value. We're helping someone.

You put the customer first, that's first principles thinking. You adjust the way you spend your time, according to your customer's needs.
